WATER DRAWER;

Application med June 23, ,1923. serial'No. 647,385.

To all Iwhom z't mag/comerm' Beit known that I, FRANK MONTGOMERY, a citizen of the United States, and resident of Port Arthur, in the ycounty of Jeerson and State of Texas., h-ave invented certain v new and useful Improvements in Water Drawers, of which the following is a specication. Y

This invention relates to automatic water drawers especially adapted for use in automatically drawing the water from beneath the oil in theoil containing tanks of reiineries.'

This invention is an improvement over the construction illustrated'in my co-pending application Serial No. 594,160, filed Oct. 12, 1922, andis especially designed with a view of simplifying the construction, maintenance and operation.

Other objects and'advantages will be apparent during thev course of the following description. Y

In the accompanying drawing forming. a part of this application and in which like numerals are employed to designate like parts throughout the same,v

Figure 1 is a longitudinal sectional view through an automatic water drawer constructed in accordance with the invention and applied to an oil tank.

Figure 2 is a perspective illustrating the connection between a pair of levers embodied in the inventiona Figure 3 is a side elevation of an oil conv taining tank equipped with the improved automatic water drawer parts being shown in section. v

Figure t is a sectional view through a slight modification of the invention.

In the drawing the numeral 5 designates a container attached to and having communication with the oil tank 4 and by reference to Figure 1 it will be seen that the outlet member 6 of the receptacle has its upper portion formed with a valve seat 7 with which a valve 8 is adapted to cooperate. More 'specifically the lower portion of the valve 8 is cone-shapedv as indicated at 10 and is adapted to flatly contact with the inclined seat 7 so as to control the flow of liquid.

Figure 1 illustrates that a pair of standards 14 are arranged in the container at lpoints spaced from the center thereof and have their upper portions pivotally connected to levers 15 as indicated at 16 The ad' jacent portions of the levers 15 -are overlapped and are formed with registering slots 18 to slidably receive a connecting pin 19 so that movement of one lever is transmitted to the other lever. A

One of the levers 15 is provided with a oat 20 having a link 21 pivotally connected to one of the levers 15 as indicated at 23 and it Awill be seen that the density of 'the liquid or the level of the same in the tank will'control the position of the float 20 and the position of the oat 20 in turn controls the position of the valve 8. The upper portion of the valve 8 has connection with a link 25 and the link is in turn connected to the outer end of one of the levers as indicated at 26.

From the foregoing description it will be seen that the level of the liquid in the container 5 controls the position of the float 20 and the .float 20 in turn automatically controls the valve 8 so that the discharge of water is automatically controlled'.

In carrying out the invention, the container 5 may be 'provided with a drain cock by means of which sediment or the like may be discharged. Also a screen or other filtering medium may be employed between.

the container 5 and the machinery to eliminate trash or foreign matter which would be likely to interfere with the operation of the valve 8.

In the form of the invention illustrated in Figures l, 2 and 3 the container 5 is formed at its upper portion with a ange 170 which may be attached by. bolts, rivets or other suitable means to the bottom of the main oil container ll. v Of course, preparatory to attaching the receptacle or container 5 to the bottom of-an oil tank the bottom of the oil tank is provided with an opening large enough to provide free and unrestricted communication between the tank andthe automatic water drawer. A suitable screen 172 extends across the top of the automatic water drawer and excludes foreign matter of a greater specific gravity than the oil and water.

In operation the water beneath the oil will raise the float 20 due to the specific gravit of the same andv more particularly the di ference in the specific gravity of the fioat 20 and the specific gravity of the Water. When the water actuates the float 20 the valve 8 will be elevated so as to allow the water beneath the Oil to be drawn o i through the discharge member 6. When the water is discharged the float 20 will return to its normal position and thereby prevent the oil from accidentally being discharged.

In the form of the invention illustrated in Figure 4, the container 180 is attached vto the oil containing tank 181 through the medium of a pipe 182, the said pipe being provided with gate valves 183 and 184, both of which control communication between the container 180 and the tank 181.

The inlet end of the pipe 182 is extended downwardly as indicated at 186 and is extended into al recess portion 187 in the bottom of the oil tank so as to receive all the water in the tank. p

The container 180 is provided with a liquid controlling mechanism 185 similar to the liquid controlling mechanism illustrated in Figure 1 and the said liquid controlling Inechanism of course controls the discharge of water through a discharge pipe 186 in the bottom of a well 187 in the container 180. Attention is directed to the fact that an emergency drawer pipe 190 is located between the valves 183 and 184 and is provided with a valve 192 by means of which the emergency discharge of liquid is controlled. By locating the valve 192 and the emergency drawer pipe 190 between the valves 183 and 184, a positive control is provided and the liquid may be directed through the pipe 182 and into the container 180 without being discharged through the emergency drawer 190. This is possible because of the arrangement of the several valves.

In carrying out the invention a vent pipe 196 is extended upwardlyv from the container 180 and is provided with a lateral branch communicating with the main tank 181 to form a means whereby the oil may be returned to the tank. l With reference to the fore oing description taken in connection wit i the accompanying drawings, it will be apparent that the automatic water drawer illustra-ted and described is especially adapted vfor use in automatically withdrawing the water beneath the oil in the oil containing tank so that the pressure of an attendantis unnecessary.

In'carrying out the invention any desired leveragemay be employed in connection with the members and preferably the ratio of 6 to 1 is employed in connection with a ten gallon power lloat. A varied-range of power can be obtained in using aoratio of 4 or 6 to 1 and the power float from one gallon up.

meas/ia Having thus described the invention, what is claimed is:

1. The combination with a container, of standards arranged therein, separate levers pivoted to the standards and having their adjacent portions overlapped andslidably and pivotally connected, a valve vconnected to ione'of the levers, and a iioat connected to the other lever and controlled by the liquid within the tank.

2. The combination with a container, of standards arranged at spaced points therein, levers pivoted to said standards Aand having their adjacent portions overlapped and pivotally and slidably connected, links connected to the outer ends of said levers', a valve connected to one ofthel links,l a ilo-at connected to the other link and constituting the main regulating medium, and a drain meniber connected to the bottom of the' container.

3. The combination with ra container, of standards arranged at spaced points therein, levers pivoted to said standards, links connected to the outer ends of said levers, a valve connected to one of the links, af'iioat connected to the other link and constituting the main regulating medium, a drain ineinber connected to the bottom of the container, and an outlet member controlled by said valve, one of said levers having its inner terminal portion forked to provide legs arranged on opposite sides of and overlapping the other levers, and means slidably-'and pivotally connecting the overlapped poiL tions of said levers.

4. An automatic water drawer comprising a liquid containing tank, a container having a pipe extending into the lower portion ot the tank, valves interposed in the pipe, an automatic discharge controlling device located in said container, a discharge pipe connected to said container and controlled by said automatic discharge controlling device, and an emergency drawer connected to said pipe, between said valves.
